| Abstract: | Annual production and life cycle of five dominant species of Chironomidae (Chironomus plumosus, Cryptochironomus sp., Tokunagayusurkia akamusi, Procladius sp.,Clinotanypus sp )were studied with samples collected monthly from April, 1996 to March, 1997 in Houhu Lake at four stations. Based on instar-frequency data, C. plumosus was nnivoltine, while the other four were bivoltine.Production rates in grams wet weight m-2 a-1 calculated by the size-frequency method were C.plumosus,2.170; Cryptochironomus sp., 0. 602; T. akamusi, s. 160; Procladius sp., 0. 964; Clinotanypussp., 0.390. Their P/B ratios were 3.9, 4.9, 4.4, 5.3 and 6.6, respectively. |
